ABSTRACT:
An electronic throttle body control system (100) and method provides accurate control over a throttle plate (102) position via various functions. An ice breaking function detects whether there is ice blocking the path of the throttle plate (102) and vibrates the throttle plate (102) to break and remove the ice. A mechanical stop confirmation function that confirms a mechanical stop position each time the vehicle is turned on to ensure that adaptation values for the throttle plate (102) are calculated accurately. A miswiring detection function detects miswirings by detecting whether the actual movement of the throttle plate (102) is in a direction opposite to the setpoint target direction.
